Definition

1. Noun:
   • A type of carbohydrate: A trisaccharide is a sugar molecule composed of three monosaccharide units linked together. It is hydrolyzed to yield exactly three monosaccharide molecules upon complete breakdown.

Usage Examples

• Noun:
  • Raffinose is a common trisaccharide found in beans and some vegetables.
  • The digestion of the trisaccharide required a specific enzyme to break its bonds.

Advanced Usage

• In Biochemistry: The term is used precisely to classify sugars based on the number of monosaccharide units. A trisaccharide is intermediate in complexity between disaccharides (two units) and polysaccharides (many units).
  • The researcher studied the transport mechanism for the trisaccharide across the cell membrane.

Variants and Related Words

• Monosaccharide (n): The simplest form of sugar, a single unit (e.g., glucose, fructose).
• Disaccharide (n): A sugar composed of two monosaccharide units (e.g., sucrose, lactose).
• Oligosaccharide (n): A carbohydrate whose molecules are composed of a relatively small number (typically three to ten) of monosaccharide units. A trisaccharide is a specific type of oligosaccharide.
• Hydrolysis (n): The chemical process of breaking a bond in a molecule using water, which is how a trisaccharide is broken down into its components.

Synonyms

• Triose sugar: (Less common, more general) This term is ambiguous as "triose" typically refers to a monosaccharide with three carbon atoms, not a three-unit sugar. "Trisaccharide" is the precise and preferred term.
• Oligosaccharide: This is a broader category that includes trisaccharides.

Related Phrases

• "Yield upon hydrolysis": A common phrase describing the result of breaking down a carbohydrate.
  • This trisaccharide yields galactose, glucose, and fructose upon complete hydrolysis.
